Female Yautja

The female Yautja are fearsome warriors just like their male brethren. Little is known about them and there are only a few notable specimens.
When they have a mate, they prefer to hunt together, sometimes even die together. They are often more calculative than males, who tend to be more reckless.
The female Yautja are usually bigger than males and some have feminine qualities, like breasts.
The female Yautja have never been featured in the movies or games, they are only in the books and graphics novels.
Here is a list of all notable female Yautja.

Sister Midnight

She breached the hull of a spacecraft that was attempting to infest Earth with Aliens.
Sister Midnight fought a DarkAlien (a Xenomorph born from a Darkling) and was badly injured.
She died while detonating her self-destruct device which destroyed the spaceship. However, she was able to complete her mission by destroying the Alien menace.

Vagouti

Vagouti was a female Yautja who traveled to Earth together with her male companion, Nakande.
Vagouti was larger and more experienced by Nakande, but they were both expert hunters or possible even retirees (wanting to make one last hunt).
They wanted to exact revenge on humans who killed their brethren nine years before in Alaska.
Together they located Sloane and Mary, two special forces snipers living a quiet life in a remote Oregon forest.
Vagouti and Nakande slaughtered a group of bikers, but failed to kill Sloane and Mary.

She was blooded by Yautja elder Dachande on the colony planet Ryushi.
Machiko Noguchi killed at least one Alien Queen and kept her head as a trophy on her wall.
